Hey Barbara- I had this when I was hospitalized for a crisis-

I wasnt allowed to eat until I came off the vent, and they then ordered it.

When i get very tired I do get a hoarse voice and feel like i have something stuck in my throat and I also feel like food gets stuck where it feels like a lump of some kind...

The test is quite easy..yet doesnt taste so good..

They make you drink some different types of drinks...i think they give you a choice not that any of them taste that good but preference wise. They have you lay on a table and have a continous X ray going on behind a glass door...

They do a few xrays at different angles (the table moves up and down vertically)

Other than that theres not much to it they have you eat some different things and see how fast it goes down..

I do remember them giving me somewhat a marshmellow s'more with some VERY nasty white paste on top..dont be surprised if you get that

If you have other questions lemme kno.
